UNITE STATES PATENT FFICE.

JOHN PETERS, OF POTTSTOWN, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO IRWINY. KRAUSE, OF SAME PLACE.

THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 390,188, datedSeptember 25, 1888.

Application filed February 10, 1588. Serial No. 963,598.

To aZZ whom, it may concern.-

Be it known that I, JOHN PETERS, a citizen of the United States,residing at Pottstown, in the county of Montgomery and State ofPennsylvania, have invented certain new and useful Improvements inThill-Oouplings; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing bad to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form apart of this specification.

My invention is adapted particularly to be used with the ordinary formof thill-coupling, consisting of a clip secured to the fore axle andhavinga bifurcated arm to which the thill-iron is coupled by means of ahorizontal bolt.

It consists of a gib and adjustable liner adapted to be placed betweenthe head of the thill-iron and the clip.

Figure 1 is a side view of an ordinary thillcoupling with my device inposition. Fig. 2 is a front view of the gib-picce, and Fig. 3 a similarview of the liner.

A represents the axle clip of the thill coupling formcd with bifurcatedarm A B is the nut on the draftbolt connecting the thill iron G with thecoupling.

O is a gib adapted to be placed in the bifurcated arm and formed with aprojeetion,O ,and a lug,O, with tapped hole C; also with a bent arm, 0,and heel-pieces The liner D is curved at the bottom D to correspond withthe head of the thill-iron, slightly dished at D and provided with anoblong hole, D, at the top.

The screw E is preferably formed with a convenient head, E, for readyadjustment,and is provided with ajam-nut,F, to lock it when properlyadjusted, if desired.

The bent arm (3 of the gib is adapted to span one side of the bifurcatedarm A and run close to the side of the nut B, so as to prevent thelatter from turning, thus serving as a lock to the draft-bolt.

(No model.)

The device may be attached or removed readily while the thills arecoupled. The combined thickness of the gib and liner on line with thedraft-bolt is designed to be somewhat less than the space between thethill-head and the clip, so that the gib may first be putin position,the liner then entered in a slanting direction and the dished part Dplaced over the projection O of the gib, which serves as a fulcrum forthe liner. The adjusting-screw is then passed through the oblong hole Dand screwed into the gib-hole C" until the lower curved face, D touchesthehead of the thillarm. This curve extends under the head so as toprevent the device from lifting out of p0- sition, though theheel-pieces G on the gib maybe used as an additional guard.

Vhen desirable,the gib and liner can be inserted from the bottom insteadof the top without material change.

The construction shown may be varied from and yet involve the mainpoints of my invention,as set forth in the following claims,which Idesire to secure- 1. In a thill-eoupling, the gib O, with intermediatefulcrum, O", in combination with the liner D, fulcrumed on said gib, andwith an adj usting-screw, all arranged and adapted to operatesubstantially as set forth.

2. In a thill-coupling, the gib O, with intermediate fulcrum, O and heelC in combination with the liner D, fulcrumed on said gib, and with anadjusting-screw, substantially as and for the purpose set forth.

3. In a thill-coupling, the gib O, with nutlock arm 0, in combinationwith the adjustable liner D, substantially as and for the purpose setforth.

In testimouy whereof I affix my signature in presence of two witnesses.

JOHN PETERS.
